Peavey Classic 30 / 50 & Delta Blues Low Output High Gain Option

The graded high current ECC83S is located closest to the power tubes.

Combo amps are very hard on tubes because of vibrations which can cause tube rattle with any brand of tube. Unlike the Classic 50 amps where the tubes are up in the chassis, the Classic 30 and Delta Blues amps have the tubes exposed and ground zero to the speakers. This can cause a lot of tube rattle. If you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings for the four EL844’s. These will greatly decrease tube rattle, however you will need to remove the wire retainers to use them.
